Dekoni Audio Earpads for Sennheiser HD600 HD650 HD660S HD6XX HD58X | Premium Replacement Ear Pads for Sennheiser Headphones | Soft, Durable, High-Fidelity Comfort Upgrade (Elite Velour)

These things are definitely worth the higher price tag. I can't compare them to other cheaper options, but I can't imagine the cheaper options doing the job better than these.Big pro: They couldn't be easier to install and they stay in place pretty well.They are SUPER comfy. The fenestrated sheepskin does not run hot at all. And this is coming from someone who runs VERY hot. Also, I never find myself having to adjust them like I did with the stock Sennheiser cushions that I was using.They also do not alter the sound much at all. If anything, they amplify the base a bit and (in my opinion) improve the sound overall.

I bought these for my (Mass)Drop HD6xx headphones because I've really worn down the original ones.Installation is a breeze--you just line the pad up in the middle and press down on the pads til you feel a click. Removing the old pads was a bit tricky. I basically tore one pad away from the mounting ring because I grabbed it wrong. The glue was probably also starting to weaken. If you're trying to keep your old ones intact, my advice would be to be certain that what you're grabbing is hard plastic, and pry up from the inside of the ring. If you do what I did and pull the pad away from the ring, a spudger or thin standard screwdriver can be used to pry the ring up from the outside of the ring so you can mount the new one. If you aren't sure whether you got the ring, the inner foam cover that sets between your ear and the driver should be loose if you got the mounting ring. If you didn't, the foam cover over the driver will be stuck in place.The new ones are a good bit thicker than the original ones, so I had to adjust the band a bit to fit comfortably. It's hard to imagine someone with a bigger head than mine, but I suppose it's possible you might max out the band before getting to a comfortable position. It's also worth noting that the sheepskin exterior is keeping my ears warmer than the solid velour original ones. You may prefer the plain velour ones if you run hot. They are less breathable than the original ones, but a good tradeoff between full sheepskin and full velour. Hopefully the foam core will hold its shape for a while, but I can't speak to that yet.I'm too old to be much of an audiophile anymore, but I will say that from my own perspective, there's not a substantial difference in the way things sound with the new ones installed vs. the original ones. I like the way my HD6xx faithfully reproduces music, and I'm pleased to say that these pads didn't affect it much, at least as far as I'm able to tell. There may be a touch more isolation thanks to the sheepskin exterior, but it's not substantial. These are open-back headphones, so that's not what I'm after when wearing these anyway.

I have found these helped the sound on my already great headphones. They are very comfortable and so glad I got thme.

Very comfortable and made with nice material. Only lasted about a year unfortunately, had the plastic break apart and the glue separated from the plastic (similar to other reviewers).Contacted Dekoni support and was told that they could replace them, so I sent the pads out and haven't heard back for 2+ weeks. I have reached out multiple times asking for an update but they have gone radio silent.Update for this review:I have since heard back from Dekoni support after reaching out a couple more times. They said they had not received the package, but after sending the tracking info they said they were sending out replacement pads. We'll see if they end up lasting longer than the old ones did.

I decided to finally replace the original pads on my HD6XX headphones. I haven't until now because about 2 years ago I mostly daily drove my Anandas, but I really wanted to experience the really warm tone of the HD6XX again so I used them for a few days. They didn't sound like I remembered, as everything just sounded kind of blunted and melded into the mids. Like I said, these were with the original pads and I think I got my HD6XXs on the second or third wave that (Mass)Drop did so yeah.... the pads were very old and pretty squished down. I was a bit skeptical of how much new pads would change the sound since I changed the pads on my AKG headphones and they didn't change that drastically. But wow was I wrong...I guess the HD6XX is much more sensitive to pad changes, because the sound is night and day. I thought I might as well give the Dekoni pads a shot since they use a different foam than Sennheiser (stock pads are pretty notorious for wearing down quickly, although most people like the stock sound the best) It's been years since I have heard the stock HD6XX pads so it's hard to compare from memory, but if I had to guess I am pretty sure I would actually prefer the Dekoni Elite Hybrid pads over the stock ones.TL;DR: the bass is accentuated a little, the mids are very slightly recessed more but still intimate, the highs are still rolled off a bit but sound a little less "veiled". The best change is that since the earpads are slightly deeper, the soundstage opens up a bit but the instrument separation is very noticeably improved. This is exactly what I wanted for my HD6XX so I love them--if these changes sound good to you, seriously just buy them already. You won't regret it.The Dekoni pads do change the stock sound, but mostly for the better in my opinion. Overall, it is still a very warm sound signature just like stock. However, there is definitely more bass presence, which I prefer. I used to have to EQ a couple db of bass to get it just where I liked it, but now I just leave my EQ flat and it sounds great. The bass is accentuated without sounding bloated, and the only time it may sound too flubby is for very bass heavy music like EDM. But if you're a bass head, you're probably not using the HD6XX anyway.As for the mids, male and female vocals still sound excellent. They are just moved a tiny bit backward into the mix since the earpads are thicker than the stock Sennheiser pads. I think this is mostly because the soundstage sounds a little more open. Don't get me wrong, it still sounds pretty intimate and has the HD6XX sound, but it is just opened up a tad more, which some may or may not like. But since replacing the pads decongested the music compared to my old squished pads, wow instruments like piano and electric guitar sound absolutely awesome. They sound very lush and present in the mix, so if you listen to a lot of rock music, then get these pads!For the highs, not too much has changed. The overall tone is still warm, but I think since these pads sound a little more open, the highs don't quite roll off as much compared to stock (again it's been years, so I could be wrong) From what I remember, these pads sound a little less "veiled" while not sounding too bright either.I think one of the best parts of these pads is the slight opening up of the soundstage, because it still has that intimacy especially with vocals, but you get a noticeable boost in instrument separation. Since the bass is more accentuated and the mids are separated a little more, you can really hear the each part more distinctly so it sounds even more detailed. You really hear all of those vocal layers if you're listening to a song with harmonies, or those little details sitting lower in the mix are a little easier to suss out. If you have some older pads like me, then switching to these pads is like shaking off the old rust and making your music shine again.The only minor gripe I have is that since the HD6XX can be a pretty clampy headphone even with stock pads, you definitely notice the clamp a bit since these earpads are a little thicker than stock pads. I am hoping my headphones break in a bit after wearing them more with the new earpads, but honestly I'm really nitpicking here. If/when these pads wear out, I am definitely buying another set because I am just in love with how these make the HD6XX sound.
